1. A method for filtering an image area performed by a video decoding device, the method comprising:
obtaining an image area having been reconstructed and a quantization parameter of the image area;
generating an embedding vector based on the quantization parameter and a prediction type of the image area; and
generating a filtered image area of the image area based on the embedding vector by using a denoising model that is based on deep learning,
wherein the prediction type of the image area indicates one of an intra prediction type in which the image area is predicted independently, a predictive type in which the image area is predicted based on a reference image area in a single direction, or a bi-predictive type in which the image area is predicted based on at least one reference image area in bi-directions.
